Topic: My RX580 Benchmarking and Results: 30.5Mh/s @ 77.5W (+ 1130MH/s Dcr w/ 125W) - page 6. (Read 189836 times)

Can't get my MSI RX 580 8Gb Gaming X (samsung) working on voltages lower than 975mv. If try to go lower than -170 in afterburner, system hangs even in 2D.
Is it the limitations of AB or I'm rather unlucky with my card. Virtually every guide on the internet says you should be able to get them working with 900mV @1150 Core freq.

Update to my initial post.

Managed to downvolt to 875 with OverdriveNtool, just had to revert any changes done with AB. (Afterburner changes relative values not absolute, so the -170 in AB was way too low to go when OverdriveN settings were applied, also it seems Overdriven doesn't overwrite every AB settings).

Getting 30Mh + 86 Lbr @117W

i just help my friend tune his MSI  card which is the same as you. can go 30.6m with others strap. The first thing you would like to you is using ddu to uninstall the driver and install the blockchain driver.

I just bought a couple of RX580's.  Is it still possible to get these to run with Claymore under Linux?

It seems that the Linux software is too new for any driver software that I can get my hands on.
Drivers keep complaining that my Xorg is too new, or that dkms code cannot be installed because some structure member no longer exists in the kernel headers, etc. The only driver that installed fine, the amdgpu-pro-17.50-511655.tar.xz  and the AMD-APP-SDK 3, do not seem to be supported by Claymore.

Just having a tough time..

Can someone please help, I have these card, MSI RX 580 ARMOR 8GB OC with Samsung memory, I copied straps 1:1750 to 1:2000 and 2:1750 to 2:2000, that pushed my stock hash from 19 to 24.5, haven't overclocked as yet. Hash rate still low though, it could be very helpful if someone knowledgeable can help.

Here is my original rom: https://mega.nz/#!jdxDnBRL!kJokqryH6FtSMfQiyIlovZxmTUcqRlgYzVjvmK_3Rts

Thanks

Have installed 8 RX 580 4GB Nitro+ Elpida memory. 7/8 cards are getting around 30.5 mh/s @ 2050 mem and 1150 core. The last card I'm not able to get past 1900 mem..i can push a bit more with error and if I set 2000+ windows crash. It is the exact same card model with memory type etc as the other card all brand new with same serial also.

I thing I noticed is that dag creation ms is higher on this specific card.

Anyone seen this or cause it ?

I have powercolor rx580 red dragon which has both 8pin + 6pin connector and I only use 8pin for each of them no problem works fine. I just need to improve my hash rate on SMOS.

Anybody can confirm the rx580 can be plugged with only one 8-pin connector ? I hope I could add a second one on a 520W power supply.

Hello. Normally people just tell you the gpu core power consumption. Mine is around 100W as i said. The system on idle uses about 100W to the wall. My cpu is a Xeon X5460 with 120W TDP, but even at full load only uses 40W according to cpuID HWmonitor, (it's way voltage downcloacked from VID numbers) so , not bad at all for a 4 cores 4 threads 8 year old dinosaur.
Yes, i use my rig for daily (it was not meant to be for mining but it is indeed now). add an 120mm AIO, 3 x120mm fans, ddr3 1,65v and not the best efficient mobo (though a good old one, like it is the Asus P5QC) and two hard drives, one SSD and 1TB hard drive. also RGB lights on the case and high performance keyboard and mice with RGB lights.

But, you should know that there are more variables. For example, the Asic Quality determines how much voltage does the card need to use, and moreover, are better overclockers and downclockers aswell. The higher asic, the better, mine is "average" at 75%.
Another variable is the memory. It's said that Samsung memory use less power than mine (Hynix memory)so there you can get a few watts less.
Another variable is the slot. cards with risers use less power according to what i've seen. very little less, but when you have 6 cards, well, it can be like 20-40W less for the whole 6 cards.

The sapphire RX 580 pulse model, as from stock uses less power, you can go way down to 0,835v using 77W and hashing nearly 30mh/s. While mine, the Nitro+ uses more core voltage so the number from which you can downclock is higher than on the pulse, even at -200mv it will not let me go below 0.925v no matter if i go to 1000mhz on the core. So, in practice, for only mining, the pulse is the way to go. Thought i think you can tell the miner to insert a certain voltage, i haven't tried it out.  

for a complete 6 RX 580 8gb cards mining rig the total power consumption according to some people is about 850W to the wall. like 125W per card (assuming idle power consumption of about 100W)This is achivable just by going to 75-80W on the core power consumption.


I can confirm, that , with my settings above, i don't need to plug the 6 pin conector, it will be perfectly fine with the 8 pin connector while hashing. i've tried even 1450mhz on the core and 2250 on mem with just 6mv added to stock voltage on the core with only the 8 pin connector and it was perfectly stable in Uniengine Heaven and 3dmark fire strike, so....there you are.

according to my numbers, my card uses while hashing a total power consumption of about 150W, Being like 100W for the core and 50W for other components. I've tried going below that, but the savings on W are very little compairing with the Mh i do not get.  

Thanks for your answer,

So, i think i will buy RX580 4Gb, it costs less

But in france we can buy RX480 ! has it any advantage ?
